Yeah, mine helps me, too! I use colored markers on the back of my cards when I need to remember the pin numbers. Since I have a horrible memory due to ADHD, depression, and anxiety, this is pretty much a life saver. Especially since my numbers all have unique colors. I've contemplated making my own font where each letter is just a square that's colored, but letters like M, D, and B might get mixed up. I'd have to almost "refine" their colors if I want to be able to tell them apart. I was also pretty good at spelling. :) Maybe this thing is a mini superpower. lol
